How to Clean Up Audio Recordings
Recorded in a noisy environment? Here's how to rescue a recording with background noise, hiss, or hum.
Common Audio Problems and Solutions
Most audio quality problems in recordings come from the environment: • Background noise (fan, AC, traffic) → Use the Noise Remover to filter it out • Recording too quiet → Use the Volume Normalizer to boost levels • Recording too long with dead air → Use the Audio Cutter to trim silence • Wrong format needed → Use the Audio Converter to change formats For the most common problem — background noise — the Noise Remover handles it in seconds.
Step by Step: Clean Up a Noisy Recording
1. Open cut.audio's Noise Remover 2. Load your recording 3. Set the strength slider — try Medium first 4. Process the file 5. Listen to the result — if noise remains, process again at a higher strength 6. Optionally, run the result through the Volume Normalizer to bring levels up 7. Export in your preferred format For best results, clean up noise first, then normalize volume. Normalizing a noisy file makes the noise louder too.
Prevention Tips for Next Time
Cleaning up after recording works, but recording clean is always better: • Turn off AC and fans before recording • Close windows to block traffic noise • Use a directional microphone pointed at the speaker • Record in a small, carpeted room — large rooms with hard surfaces create reverb • Keep your mic close to your mouth (6-8 inches) — the closer the mic, the better the signal-to-noise ratio • Do a test recording and listen back before the real thing

Echo (reverb) is harder to remove than steady background noise. The noise remover can reduce some room reverb, but heavily echoing recordings may not clean up completely. For best results, record in a treated or carpeted room.
Before. Denoise the raw recording first, then edit (cut, join, etc.). This way the noise removal works on the original signal before any other processing.
